I find the Bandmaster to be pretty comparable as a little brother Bassman... breaks up earlier, definately not as loud and not quite as massive sounding... gets the dirt going sooner and has a bit more sag near the end of the volume, but the feel and tone to me (especially with the tweeds) is quite similar to my ears.

I have a tweed Super clone, have played other clones, and the real thing too, and those are still very loud if you want breakup at home levels IMO. Sound different than a bassman too, but they're in that ballpark, kind of.

6L6's and that big output transformer are a big part of a Bassman's sound IMO, and short of an attenuator, those don't really "come in a quieter version"...
